      $.ajax({
         type: "POST",
         url: 'process/process_mst.php?action=supplier_create',
         data: "sec_supplier=" + $('#sec_supplier').val() + "&sec_branch=" + $('#sec_branch').val()

         + "&sec_amount=" + $('#sec_amount').val() + "&sec_desc=" + $('#sec_desc').val()
         + "&sec_user_id=" + $('#sec_user_id').val(),
         success: function(data){
         error = '';
         if($('#sec_supplier').val() == "")                 
             error += ' - Please select supplier';
         if($('#sec_branch').val() == "")                   
         error += ' - Please select branch';

         if(error != '')
    alert(error);
    else{
    alert("Data inserted...");
    window.location = "support_entry.php";
         }
       }
     });            
    });             
  });
</script>
